This invention relates to floor drains and the object of the invention is to provide a non-clogging floor drain having a sediment intercepting basket and arranged to allow flow through the drain even when'the basket is clogged with sediment.

Another object of the invention is to provide a floor drain having a sediment intercepting basket providedwitha tubular centralportion over i which the grating extends, the arrangement being such that upon clogging of the sediment basketL the water may still flow through the grating-I and through the tubular portion of the basket.

A further object of the invention is vto provide a oor drain in which the grating cannot be used unless the sediment intercepting basket is in position.

Another object of the invention'is to provide a '-A floor1 drain having a flashing clamp and arranged so kthat any seepage will pass into-the interior of the drain.

A further object of the invention is to provide a oor drain having a sediment intereepting -Y basketformed of metal and provided with overflow apertures and having agrating tting over the top of the basket and provided with an annular apron extending into the basket, the basket being also provided with a tubular portion 30.1at the center opening into the drain bodyat the lower end and the grating being provided with an apertured portion tting over the upper end Y of said tubular portion.

These objects and the several novel features of 35.-!theinvention are hereinafter more fully described and claimed and the preferred form of constructionby which these objects are attained is shown in the accompanying drawing in which- Fig. 1 is a longitudinal section through -a iioor eidrainembodying my invention. Y

Fig. 2 is a section taken on line 2 2 of Fig. 1. VAs shown in Fig. 1`, the drain comprises a cylindrical drain body I having an outlet12-at the bottom and provided with a vent connection 3 45 near the top. This drain body is provided with an angular ange 33 extending thereabout and with a series of seepage apertures 4-above theV junctionV of the flange with theV drain body. A clamping ring 5lis provided having-an angular 50 face extending atthe samefangle as the flange 3 and agseries of fsupporting brackets 6 are secured about the upper 'end of the drain body. Each bracket `I5 carries an adjustablescrew-'I and in the usual floor construction aleadflashing 8 is em- 55n .beddedYV in the. Aconcrete floor. Sfiandis tted. over (Cl. V182-31) the flange 3 so that by tightening the screws 1 the clamping ring 5 will be pressed downwardly to engage the flashing tightly against the angular flange 3. The clamping ring 5 has its inner face spaced from the upper end of the drain body I and Water may pass through the concrete into the space 3 and thence through the seepage apertures Il into the interior of the drain body.

On the inside of the drain body near the top is an annular flange 28 shaped to provide a channel 29 as shown. The sediment intercepting basket Ii is provided with a iiange II tting in the channel 23 and with a flange I2 extending ilush with the upper edge of the drain body when mounted in position v'as shown in Fig. 1. 15

This sediment intercepting basket is provided with a series of vertical slots i3 in the outer wall spaced above the bottom thereof and at the center is provided with a tubular portion I4 opening at the bottom into the interior of the drain body.

The grating I5 shown in Figs. 1 and 2 is seated on the shoulder I6 of the sediment basket and is provided with a skirt l'l extending downwardly into the seepage basket below the overflow slots I3. At the center, the grating I5 is provided with a flange I8 fitting about the upper end of the tubular portion Ill of the seepage basket and thisV grating is'provided witha seriesof drain aperturesk I 9 over the tubular portion I4.

By this arrangement, any seep-age through the floor 9 will pass along the flashing 8 and downwardly through the apertures Irinto the interior of the drain body. The surface water will pass through the slots 20 in the grating into the seep-V age intercepting basket and as this water rises 3 above the bottom of the slots I3 it will pass through the slots into the interior of the drainA Y body.

As thev bottom of the slots extend above the lower edge of the skirt. II, water is maintained in the seepage basket above the lower edge of the skirt. I'I and provides a trapfor sediment such as sticks, coal7 ashes, mud, sand, bottle caps, broken glass, feathers, clippings, etc. which will remain in the sediment basket and when the sediment basket becomes cloggedwith such sediment so that water will not pass therethrough the surface. water will fill the seepage .basket up to the level of the grating and will then pass to the center of the grating-and through the apertures i9 and thence through the tubular portion I4 into the interior of the drain so that drain-age is A provided even when the sediment basketV is clogged.

To clean thesediment basket it is merely. necessary to lift the grating I and then lift the basket out and dump it, at which time, the parts may be replaced in position for further use. It is to be noted that the grating cannot be used without the Y sediment basket in place as the grating willnot properly t when the sediment basket is removed.

' This drain body, sedimentintercepting basket andV tubular portion I4 shown in full lines in Fig. 1 are serviceable in many installations where escape of gases through the apertures of the cover is not important. However, where the escape of gases is 'an important factor, the flange I I 'be formed, as indicated by dotted lines 50 in Fig.

1, to extend downwardly into the drain body Vbelow, the normal water level determined by the outlet. By the described arrangement Yof parts including that indicated by the dotted lines 50, escape of gases through the grating into a room of a'building is prevented.

From the foregoing description it becomes evident that the device is verysimple and `efficient in operation, provides a floor drain which may be readily cleaned at anytime Vwithout tools, will prevent sediment from passing into the drain and provides a device which accomplishes the objects' described.
